WARNING

If you experience issues with users that are chrooted into a directory, this may be because (a) your users have a shell set to /bin/false and/or (b) because the chroot itself is not writable. The solution is then to add the following line into your /etc/vsftpd/vsftpd.conf file:

# the virtual user is restricted to the virtual FTP area
# --- STANDARD CHROOT COMMAND ---
chroot_local_user=YES
# --- ADD THIS LINE TO MAKE THE CHROOT WRITABLE ---
allow_writeable_chroot=YES
